Snowboard binding with improved deck connection

ABSTRACT

A snowboard binding, comprising a base plate which has a cavity for accommodating a disk adapted to allow the connection between the base plate and the snowboard deck, the disk having an elongated shape with the central regions provided with recesses, the cavity of the base plate having complementary protrusions adapted to mate with the recesses of the disk.

The present invention relates to a snowboard binding with improved deck connection. More particularly, the invention relates to a snowboard binding that can be connected to the deck while maintaining its natural flexing.

BACKGROUND OF THE INVENTION

As is known, snowboard decks are used with what is called a soft binding and are constituted by a base that is fixed to the deck and by a spoiler that is connected to the base. The foot of the user is accommodated within the base and is fixed by means of straps.

The base of the binding is fixed to the deck by using a disk that is accommodated in a circular opening formed within the base of the binding, the disk being fixed to the deck by means of screws and at the same time locking the base of the binding to the deck.

The disk is normally provided with a set of teeth that allows positioning the base in different angular positions so as to be able to provide the user with the position that he desires.

The drawback observed with ordinary binding types is that most of them have an extensive contact surface between the binding and the snowboard deck; this is due mainly to the mounting system with circular disks, which uses four screws to fix the base of the binding to the deck.

This extensive contact surface of the base of the binding or base plate and the deck blocks the natural flexing of the deck, i.e., the flex of the deck.

Essentially, the larger the surface of the disk and of the base of the binding that rests on the deck, the larger the so called “dead” zone thereon, i.e., the region where flex is eliminated.

SUMMARY OF THE INVENTION

The aim of the present invention is to provide a snowboard binding that has such a deck fixing system as to make it possible to maintain natural flexing as much as possible.

Within this aim, an object of the present invention is to provide a snowboard binding that has the smallest possible contact surface with the deck.

Another object of the present invention is to provide a snowboard binding that has a deck fixing system which uses the smallest possible number of screws.

Another object of the present invention is to provide a snowboard binding that allows the user to adjust the angle of the binding, like bindings of the known type.

Another object of the present invention is to provide a snowboard binding that is highly reliable, relatively simple to provide and has competitive costs.

This aim, as well as these and other objects that will become more apparent hereinafter, are achieved by a snowboard binding, comprising a base plate which has a cavity for accommodating a disk adapted to allow the connection between said base plate and the snowboard deck, characterized in that said disk has an elongated shape with the central regions provided with recesses, said cavity of the base plate having complementary protrusions adapted to mate with said recesses of the disk.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

With reference to the figures, the snowboard binding according to the invention, generally designated by the reference numeral 1, comprises a base plate 2 that is adapted to be connected to a snowboard deck 3. Conveniently, the base plate has a central cavity 4 that is adapted to accommodate a disk that makes it possible to fix the binding to the deck by fixing said disk to the deck.

Conveniently, the disk, designated by the reference numeral 5, has a generally elongated shape, with recessed central regions 6 and 7, so as to form a flattened elongated portion.

The disk 5 has a pair of holes 8 and 9 adapted to allow the fixing, by means of respective screws 10 and 11, of the disk 5 within the cavity 4 to the deck 3.

Conveniently, the disk 5 is provided, at its front and rear ends, with a knurling or set of teeth 13 and 14 that is adapted to engage a corresponding set of teeth 15 and 16, respectively, formed at the cavity 4.

Conveniently, the cavity 4 is shaped complementary to the disk 5 and therefore, at the regions 6 and 7 of the disk, which are recessed, there are protruding regions 17 and 18 adapted to allow the disk 5 to be accommodated perfectly within the cavity 4.

The fixing of the disk to the base plate 2 and therefore to the deck 3 occurs by using only two screws 10 and 11 arranged substantially along a line that crosses transversely the base 2 of the binding and the deck 3.

The region for fixing the disk 5 to the deck 3 is therefore reduced to the minimum indispensable size by providing the recessed regions 6 and 7 and by limiting the set of teeth 13 and 14 at the front and rear ends of the elongated disk 5, i.e., at the regions where the the user normally performs the adjustment.

The protruding regions 17 and 18 of the base plate 2 act as stiffening for the base plate 2 of the regions that are not kept under pressure by the disk 5 and also act as rotation limiters for the disk 5.

Essentially, therefore, the disk cannot rotate beyond the region defined by the sets of teeth 15 and 16 formed on the base plate 2 of the snowboard binding, without limiting however the choice of the angular position of the base plate within the normal positions for use.

In practice it has been found that the snowboard binding according to the present invention achieves fully the intended aim and objects, since it makes it possible to maintain, despite being fixed to the deck, the natural flexing of said deck, since the binding fixing region is limited to the smallest possible size, and the connection of the binding to the deck occurs by using substantially two screws arranged substantially in axial alignment with the transverse axis of the deck.

The so-called “dead zone” that is thus normally created as a consequence of the connection of the snowboard binding to the deck itself is absolutely limited to the minimum possible size with respect to what instead occurs in the connection of snowboard bindings of the known type to snowboard decks.

The invention thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the accompanying claims; all the details may furthermore be replaced with other technically equivalent elements.

In practice, the materials used, as well as the contingent shapes and dimensions, may be any according to the requirements and the state of the art.

What is claimed is:
 1. A snowboard binding, comprising a base plate which has a cavity for accommodating a disk adapted to allow the connection between said base plate and the snowboard deck, wherein said disk has an elongated shape with the central regions provided with recesses, said cavity of the base plate having complementary protrusions adapted to mate with said recesses of the disk.
 2. The snowboard binding according to claim 1, wherein said disk has a pair of holes adapted to allow the fixing of the disk, within the cavity of the base plate, to the snowboard deck by means of a pair of screws.
 3. The snowboard binding according to claim 1, wherein said disk has, at its front and rear ends, toothed regions adapted to mesh with corresponding toothed regions formed at the front and rear regions of the cavity of said base plate, thus allowing a broad choice of angular placements of the base plate of the binding on the deck.
 4. The snowboard binding according to claim 1, wherein said disk has lightening regions that are formed by cavities arranged substantially along the original extension of the disk.
